DEVICE FOR HOLDING A MODEL CARRIER OF AN ABUTMENT MODEL

The invention relates to a device for hauling a model carrier of an abutment model, an insert for holding a model carrier of an abutment model, a pot for receiving an insert for holding a model carrier of an abutment model, a device for scanning, a method for scanning, a method for manufacturing an abutment, a method of making a dental prosthesis that includes an abutment, and a computer-readable medium.

Devices are known for scanning tooth models in order to obtain a data set representing the tooth model. These data records can be used for the automated production of dental prostheses.

In addition, the modeling of dental prostheses, such as an abutment, known. An abutment is part of a dental care that is applied to an implant. For example, a crown or bridge can be placed on the abutment.

The object of the present invention is to specify means and methods with which an automated production of individual abutments or other tooth replacement parts is made possible. This object is achieved with a device according to claim 1, an insert according to claim 12, a pot according to claim 30, an apparatus according to claim 38 or 40, a method according to claim 41 or 42, a method according to claim 48, a method according to claim 49 and a computer readable medium according to claim 51. Preferred embodiments are disclosed in the subclaims.

A device for holding a model carrier of an abutment model may comprise a holder and a receiving device, wherein the holder may comprise at least one magnet and / or a magnetic material and wherein the holder may be placed on the receiving device and wherein the holder with respect to the receiving device variable can be positioned. Since no precise positioning of the holder with respect to the receiving device is necessary, the positioning can be done very easily, for example, even without tools. This is advantageous, for example, in the case of non-rotationally running scanning methods, in particular in the case of at least partially translatory scanning methods with, for example, Cartesian coordinate systems, in which, for example, no exact centering relative to an axis of rotation is necessary.

The holder may comprise at least one magnet and the receptacle may comprise at least one magnet and / or material attracted by the at least one magnet of the holder or in another embodiment the holder may comprise at least one magnetic material and the receptacle may comprise a magnet. The magnetic interaction between the holder and receiving device can allow a limited prepositioning effect, which allows, for example, a tool-free positioning. In the device according to the invention, the holder and the receiving device can each be shaped so that a variable positioning is possible only within a limited range. This serves, for example, to give a clue to a software which has to process acquired sampling data, within which region of the sampling data it is to search for specific characteristics. The area may, for example, be more than 1, 2 or 3 mm and / or less than 7, 6, 5, 4 or 3 mm in one spatial direction and / or in two and / or in three mutually perpendicular spatial directions.

A restricted pre-positioning effect can also be caused, for example, by at least two oppositely oriented magnetic pole pairs. The magnetic pole pairs may be arranged to repel in a pair combination and tighten in a different pair combination. In a preferred embodiment, at least two different magnetic poles can be provided on the holder and at least two different magnetic poles can be provided on the receiving device.

In this case, the area to which the variable positioning is restricted may be different in different spatial directions. For example, the receiving device may be located in the xy plane and may comprise, for example, a groove oriented in the x direction or the recess otherwise formed and / or raised. The aufzusetzende holder may include a correspondingly opposite shaped groove, recess and / or increase. If the holder is then placed on the receiving device, then the positioning of the holder in the y-direction may be restricted, but in the x-direction further (in some cases sem circumference) remain variable. Again, the software facilitates the recognition of certain features, but the handling remains simple.

For example, the distance between the holder and the receiving device may be fixed by the shape of the holder and the Aufnahrneeiπrichtung. For example, if the device is scanned from the holder and the receiving device, then no adjustment of the distance of the scanning device is necessary, whereby the scanning process can be simplified.

The holder and / or the receiving device may each comprise at least one groove, a groove, a hole, a pin, a pin, a recess and / or an elevation. ₍ This allows a relative position of the holder and receiver to be determined, as well as to limit the variable positioning of the holder with respect to the receiver.

In this case, the at least one groove, the at least one groove, the at least one hole, the at least one pin, the at least one pin, the at least one recess and / or the at least one elevation of the holder may be formed opposite to those of the receiving device.

The holder may comprise a first and a second region, wherein the first region comprises a flat surface, wherein on or in the flat surface there is a step, in the center of which there is an area having a connection geometry of an implant and on which Model support of the abutment model can be placed and wherein the second region comprises means which allow the positioning of the holder. By way of example, the height of the abutment model relative to the connection geometry can be determined on the basis of the step.

In addition, the holder may comprise an optically detectable marker. By means of such a marking, for example, the position of the model carrier of the abutment model relative to the marking and / or the connection geometry of the implant can be identified very precisely.

Furthermore, the holder may comprise in the first region at least one gripping device, which preferably extends from the flat surface. By means of this gripping device, the holder can be gripped, for example, to be placed on the receiving device, but the gripping device can also be used to move the holder. An insert for holding a model carrier of an abutment model may include a first and a second region. The first region may comprise a flat surface, wherein on or in the planar surface there may be a step in the center of which there may be an area which may have the connection geometry of an implant and on which the model carrier of the abutment model can be placed. The second area may include means that may enable positioning of the insert. In addition, the insert may comprise an optically detectable label.

The insert may have at least one magnet in the second region. The magnet of the insert may serve to pull the insert into another component or to another component which also comprises a magnet, wherein the other component may receive the insert, for example.

In particular, the insert described above may be provided as a holder as used in the above-described device for holding a model carrier of an abutment model.

The at least one magnet in the second region of the insert may be located below the region which has a connection geometry of the implant and on which the model carrier of the abutment model can be placed when the flat surface of the insert lies horizontally and faces upwards. The insert may, for example, also comprise two, three, four or more magnets in the second region. The one or more magnets in the described embodiments allow a flexible and easy-to-handle mounting of the insert. In this connection, reference is made to the oppositely oriented magnetic pole pairs as described above.

The optically detectable mark can be on the flat surface. As a result, it can be avoided that the marking is covered, for example, by the model carrier of the abutment model.

The cross section of the insert may be circular. The cross-section of the insert may also be square, rectangular, triangular, hexagonal, polygonal or elliptical or otherwise shaped.

The insert may include at least one groove, a groove, a hole, a pin, a pin, a recess and / or an elevation in the second region. As a result, a rela- tive location of the mission. Existing in another component, in which the insert can be used for example, corresponding opposite shaped grooves, grooves, holes, pins, pins, recesses and / or elevations, so the relative position of the insert can be determined in relation to the other component.

For example, the insert in the second region may, for example, comprise two grooves, grooves, holes, pins, pins, depressions and / or elevations, which may preferably have different dimensions.

The insert may have in the first region at least one gripping device, which may preferably emanate from the flat surface. The gripping device may serve to grip and / or move the insert. In addition, the gripping device can be designed so that the position of, for example, the step and / or the optically detectable mark relative to the gripping device is clearly defined.

The at least one gripping device can protrude obliquely starting from the flat surface. Due to the oblique course of the gripping device, for example, a covering of the area with the attached model carrier of the abutment model can be avoided.

The at least one gripping device can protrude beyond a boundary of the flat surface. As a result, a cover, for example, the optically detectable mark can be avoided.

The optically detectable mark of the insert may be equidistant between an edge of the step and an edge of the planar surface. By determining the relative position of the optically detectable mark, for example, a scanning operation for detecting the mark can be limited to a certain area of the flat area and therefore simplified.

The optically detectable marker may comprise a pin, a pen, a hologram, a bar code, a pattern code, a groove, a groove, a depression, an elevation, a sphere, a hemisphere, a conical and / or pyramidal shape. Several of these different possible markings, of the same or different kind, are possible together. With such markings, the position of a model carrier of an abutment model relative to the marking can be identified very precisely. The flat surface of the insert may have a geometric pattern. The pattern may comprise, for example, lines, circular, angular and / or polygonal surfaces or another shape, wherein these lines, surfaces and / or other shapes stand out, for example, in color from the other regions of the planar surface. A difference in color may result from different shades of gray including black and / or colored paint. The geometric pattern can also result, for example, from depressions and / or elevations, wherein the depressions and / or elevations can have different shapes, colors and / or dimensions. By the geometric pattern on the flat surface of the insert and / or the model carrier of the abutment model, for example, a relative position of the insert can be determined precisely.

The geometric pattern may be symmetrical, rotationally symmetric and / or asymmetrical. For example, identical geometric patterns on the flat surface may be used for the same model carriers, but different patterns may be used for the same model carriers.

The flat surface of the insert may be circular, square, rectangular, triangular, hexagonal, polygonal or elliptical or otherwise shaped.

The flat surface of the insert can be aligned horizontally in a working position. Due to the horizontal orientation of the flat surface, it is possible, for example during a scanning operation of the mounted model carrier of the abutment model, to avoid covering certain areas.

The insert may have an insertion bevel in the second region. The insertion bevel may serve to facilitate fitting the insert into another component that can receive the insert.

A pot for receiving an insert according to the invention may comprise in, under and / or on a bottom surface of the pot at least one magnet and at least one depression and / or at least one elevation. The at least one magnet of the pot can serve to pull the insert, which comprises at least one magnet in the second region, into the pot. The at least one depression and / or elevation in, under and / or on the bottom surface of the pot can serve to determine the relative position of pot and insert within a certain framework. Due to the shape and / or dimension of the At least one recess and / or the at least one increase, the relative position of pot and use, for example, be set to less than 5, 4, 3, 2 or 1 mm. Also, the relative position for positioning may be variable in a range of more than 1, 2, 3, 4 or 5 mm. The at least one recess and / or the at least one elevation may comprise a groove, a groove, a bridge, a hole, a pin and / or a pin.

The pot may have a depression, elevation and / or marking at an upper edge. This makes it possible to determine a relative position of the pot, wherein the position can serve as a reference for example in a device for scanning.

The pot may have at least one web on an outer side. The at least one web can for example define the positioning of the pot and / or be used to hold the pot. For example, the pot in the lower region (i.e., in the region of the bottom surface) may also comprise an insertion bevel.

The pot can accommodate an insert according to the invention. As a result, a simple handling of the insert and / or the composite pot and use can be ensured.

The at least one magnet of the pot and the at least one magnet of the insert can pull the insert in the direction of the pot. This makes it possible, for example, to facilitate the introduction of the insert into the pot.

The at least one magnet of the pot and / or the at least one magnet of the insert can for example also consist of a material which is attracted by a magnet. If, for example, two areas for magnets are provided in the insert and pot, the insert may for example comprise two magnets and the pot may comprise two areas with a material which is attracted by the magnets. However, it is also possible, for example, for each insert and the pot to comprise a magnet and a region with a material which is attracted by the magnets. In this connection, reference is made to the oppositely oriented magnetic pole pairs as described above. The at least one gripping device of the insert may project beyond the upper edge of the pot, and the at least one gripping device may preferably have no contact with the upper edge of the pot.

The flat surface of the insert may be in the assembled state of pot and insert within the pot, i. the flat surface of the insert does not protrude beyond the top edge of the pot. The optically detectable marking of the insert may project beyond the upper edge of the pot, but it may also be within the pot or be flush with the upper edge of the pot. If the flat surface comprises various optically detectable markings, these may be located inside the pot, protrude beyond the upper edge of the pot and / or terminate with the upper edge of the pot. For example, the flat surface of the insert but also complete with the upper edge of the pot or protrude beyond the upper edge of the pot.

An apparatus for scanning may comprise a scanning device and at least one pot according to the invention.

Furthermore, the device for scanning may additionally comprise at least one insert according to the invention. This makes it possible, for example, to hold a model carrier of an abutment model and scan it by means of the device.

Furthermore, the device for scanning can comprise at least one device according to the invention for holding a model carrier of an abutment model. As a result, it is also possible, for example, to hold a model carrier of an abutment model and scan it by means of the device.

In a method for scanning at least one abutment model can be scanned by means of the scanning device according to the invention, wherein the at least one abutment model can be placed on at least one insert according to the invention or can be held by a device according to the invention for holding a model carrier of an abutment model. By using the insert, a precise determination of, for example, the position of the abutment model relative to the connection geometry of an implant and / or the height of the abutment model can take place relative to the connection geometry. For example, a holder or an insert can be provided for a plurality of connection geometries on each of which a model carrier of an abutment model can be placed. For a particular model carrier thus the appropriate holder can be selected without having to replace a connection geometry in the holder or in use, since, for example, each of the plurality of connection geometries is assigned a holder or an insert. Without this assignment, for example, an exchange of a connection geometry of an insert would be necessary if a different connection geometry was to be used.

The position of the at least one abutment model can be determined relative to the connection geometry of the at least one insert on which the at least one abutment model is placed.

A height of the at least one abutment model can be determined relative to the connection geometry in which the step of the insert is also scanned in the method. The connection geometry can extend beyond the step, whereby the relative position is defined. If the step is also scanned during the scan, the height of the attribute model relative to the connection geometry can be determined therefrom.

A relative spatial position of the at least one abutment model can be determined in relation to the connection geometry of the at least one implant, in which the optically detectable marking of the insert is also scanned. The defined relative position of the marking and connection geometry and the resulting relative spatial position of the abutment model in relation to the connection geometry can be used for further processing.

During scanning, measurement data can be obtained, preferably shape data, which can specify the geometry of an abutment. With the help of this data, a corresponding tooth replacement part can then be created.

The measured data can be stored and / or forwarded. The measured data can also be evaluated in order, for example, to record the geometry of the abutment on the one hand, and the relative position of the abutment model and connection geometry, on the other hand. In addition, the creation of the dental prosthesis part and / or the scanning can be done at other locations than the evaluation of the measured data. The steps can also be carried out in the same place. In the method for scanning, which scans, for example, an abutment model by means of the scanning device according to the invention, the insert comprising the abutment model can be located at any position within a range which the device scans. Thus, for example, it is possible to use a plate or otherwise shaped receiving device on which the insert or inserts can be applied. Also, one or more pots according to the invention, each comprising one or more inserts according to the invention, can be applied to the plate or to the receiving device. However, for example, certain areas of the plate or the recording device can be defined for the scanning, which are then to be scanned.

In a method for producing an abutment, an abutment model can be scanned by the method according to the invention for scanning, wherein an outer shape of the abutment can result from the measured data of the scanned abutment model. The abutment can then be modeled on the basis of the measured data. In addition, a connection geometry of the abutment can be modeled, so that the abutment can be placed on the connection geometry of a corresponding implant.

In a method for producing a dental prosthesis part comprising an abutment, an abutment model can be scanned by the method according to the invention for scanning, wherein an inner shape of the dental prosthesis part can result from the measured data of the scanned abutment model. For example, a crown or a bridge or other can be placed on the abutment.

The dental prosthetic item may be made of, but not limited to, plastic, glass fiber reinforced plastic, glass fiber reinforced copolyamide, cobalt or cobalt alloy, chromium-cobalt alloy, titanium or titanium alloy, gold or gold alloy, ceramic, zirconia or alumina ,

The connection geometry 7 can also be round, triangular, octagonal, rectangular or otherwise shaped. Figure 1c shows a representation of the insert 1 of Figure 1a from below. An inner hollow cylinder 11 is surrounded by an outer cylindrical wall 9, the outer wall 9 having two recesses 8a, 8b. The inner hollow cylinder 11 comprises a region 12 into which, for example, a circular magnet can be introduced. However, the inner hollow cylinder and the corresponding magnet can also have a different cross-section than circular, for example triangular, square, rectangular, elliptical or otherwise.

It can be used different inserts with different shapes and different connection geometries, wherein each insert is preferably fixedly connected to an insert. A so-called Wax Up Sleeve (model carrier) can be applied to the insert part of the insert (see also FIG. 5), around which an abutment model can be modeled.

Figure 2a shows a schematic representation of a pot 13 for receiving an insert 1 for holding a model carrier of an abutment model in a side view. This pot 13 represents an example of a general receiving device of a holder. The pot 13 has on the outside of a plurality of webs 15, which may for example define the positioning of the pot 13 and / or can be used to hold the pot 13. The illustrated pot 13 also has an insertion bevel 16 in the lower region. The pot 13 may also include only one web 15.
